Chops

: : : This is one I use a lot myself, but it's just occurred to me to wonder where on earth it comes from. It means to talk a lot, go on a lot, carry on a lot, etc.
: : : Is it rhyming slang? Anyone know?

: : I don't think it's a Jewish expression.

perhaps there is the double meaning of "chops" - one's chops are ones jowls or more loosely the mouth - also extensive side-burns were called "mutton-chop whiskers" after their shape.

with the discussion of the verb "to pork" earlier - perhaps 'porking the chops' has something wet and messy connotations?
